Performance Analysis of Low-Density Parity Check Codes for 5G Technology

In the contemporary world, the need for mobile internet has been increasing progressively, and this increase in demand forces an urgent requirement for 5G wireless communication. In comparison to 4G, the modern 5G cellular system is described by three sets of key use cases, which are Enhanced Mobile Broadband (EMBB), Ultra-Reliable and Low Latency (URLLC), and Massive Machine Type Communications (MMTC), and all these cases require higher throughput, reduced latency, and high reliability. Channel coding improves the efficiency of wireless communication by adding some extra bits to the information to be transmitted in a controlled manner, thereby increasing the efficiency of the communication. The two-channel codes that are receiving more and more attention because of their capacity-achieving capability are Low-Density Parity Check (LDPC) and Polar codes. LDPC codes have been chosen as the candidate codes for data channels because of their high parallelism encoding and decoding, which can realize higher throughput encoders and decoders, whereas polar codes have been selected for control channels as control signals are transmitted at a lower rate and these codes offer good performance in the low block error rate regime.
